Crystal structure of the tetra-meth-yl(pheneth-yl)cyclo-penta-dienylmolybdenumtricarbonyl dimer.

ABSTRACT: The structure of the dimer bis-{tricarbon-yl[?⁵-tetra-meth-yl(pheneth-yl)cyclo-penta-dien-yl]molybdenum}(Mo-Mo), [Mo₂(C₁₇H₂₁)₂(CO)₆], at 102?K has triclinic (P ) symmetry. The reaction between tetra-meth-yl(pheneth-yl)cyclo-penta-diene and molybdenum hexa-carbonyl in refluxing xylenes for 18?h led to a 56% yield of the dimer as a red solid. The asymmetric unit of the structure is the tetra-meth-yl(pheneth-yl)cyclo-penta-dienylmolybdenumtricarbonyl moiety and the entire dimeric mol-ecule is generated by inversion symmetry. The Mo-Mo bond length is 3.2773?(3)?Å, a value slightly above the mean value for all [CpMo(CO)₃]₂ compounds listed in the CSD and slightly below the mean for [Cp*Mo(CO)₃]₂ complexes.

Crystal structure of 3-(3,4,5-tri-meth-oxy-phen-yl)-1,2,3,4-tetra-hydro-cyclo-penta[b]indole-2-carb-oxy-lic acid.

Project description:In the title compound, C21H21NO5, obtained from a Morita-Baylis-Hillman adduct, the hydrogenated five-membered ring adopts a shallow envelope conformation, with the C atom bearing the carb-oxy-lic acid substituent deviating by 0.237 (1) Å from the mean plane of the other four atoms (r.m.s. deviation = 0.007 Å). The dihedral angle between the fused ring system (all atoms; r.m.s. deviation = 0.057 Å) and the pendant trimeth-oxy benzene ring is 66.65 (3)°. The C atoms of the meta-meth-oxy groups lie close to the plane of the benzene ring [deviations = 0.052 (1) and -0.083 (1) Å], whereas the C atom of the para-meth-oxy group is significantly displaced [deviation = -1.289 (1) Å]. In the crystal, carb-oxy-lic acid inversion dimers generate R 2 (2)(8) loops. The dimers are connected by N-H⋯O hydrogen bonds, forming [011] chains. A C-H⋯O inter-action is also observed.

Crystal structure of [3,10-bis-(4-fluoro-pheneth-yl)-1,3,5,8,10,12-hexa-aza-cyclo-tetra-deca-ne]nickel(II) diperchlorate.

Project description:The square-planar nickel(II) title complex, [Ni(C24H36F2N6)](ClO4)2 or [NiL](ClO4)2 (L = 3,10-bis-(4-fluoro-pheneth-yl)-1,3,5,8,10,12-hexa-aza-cyclo-tetra-deca-ne) was synthesized by a one-pot reaction of template condensation and its X-ray crystal structure was determined. The nickel(II) ion lies close by a twofold axis and the complex displays whole-mol-ecule disorder. Ligand L, a hexa-aza-cyclo-tetra-decane ring having 4-fluoro-phenethyl side chains attached to uncoordinated nitro-gen atoms, adopts a trans III (R,R,S,S) configuration. The average Ni-N bond distance is 1.934 (9) Å, which is quite similar to those of other nickel(II) complexes with similar ligands. The nickel(II) ion is located 0.051 (7) Å above the least-squares plane through the four coordinated N atoms. The average C-N bond distance and C-N-C angle involving uncoordinated nitro-gen atoms are 1.425 (12) Å and 118.0 (9)°, respectively, indicating a significant contribution of sp 2 hybridization for these N atoms. The inter-molecular N-H⋯O, C-H⋯O/F hydrogen bonds of the complex form a network structure, which looks like a seamless floral lace pattern.

Project description:The mol-ecular structure of the title compound, C22H38Si2, features a trans arrangement of the cyclo-penta-dienyl rings to avoid steric strain [C-Si-Si-C torsion angle = -179.0 (5)°]. The Si-Si bond length is 2.3444 (4) Å. The most notable inter-molecular inter-actions in the mol-ecular packing are C-H⋯π contacts that lead to the formation of wave-like supra-molecular chains along the b axis.

Project description:The title compound, [Ir(η(5)-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinyl-idene-pyridine ligand is N,N-coordinated through the N-pyridyl and N-hydrazinyl-idene groups forming a five-membered metallacycle. An intra-molecular C-H⋯Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C-Cl⋯π inter-actions, forming a dimeric structure. The crystal packing is further stabilized by weak inter-ionic C-H⋯π inter-actions.

Project description:The crystal structure of the title compound, [Hf(C10H15)2(C4H9)2], reveals two independent mol-ecules in the asymmetric unit.

Crystal structure of 2,3,5,6-tetra-kis[(methyl-sulfan-yl)meth-yl]pyrazine.

Project description:The title compound, C12H20N2S4, synthesized by the reaction of 2,3,5,6-tetra-kis-(bromo-meth-yl)pyrazine with sodium methane-thiol-ate, crystallizes with a half -mol-ecule in the asymmetric unit. The whole mol-ecule is generated by inversion symmetry; the inversion centre being located in the centre of the pyrazine ring. The mol-ecule has an S-shaped conformation with two (methyl-sulfan-yl)methyl substituent arms directed above the plane of the pyrazine ring and two below. The C(H3)-S-C(H2)-C(aromatic) torsion angles are 70.47 (18) and -67.65 (17)°, respectively. In the crystal, mol-ecules are linked via weak C-H⋯S hydrogen bonds, forming chains along [001] and enclosing R 2 (2)(12) ring motifs. The chains are linked by further weak C-H⋯S hydrogen bonds, forming sheets lying parallel to (101).

Bis(η(5)-penta-methyl-cyclo-penta-dien-yl)aluminium tetra-bromido-aluminate.

Project description:The title compound, [Al(C10H15)2][AlBr4], was formed during the reduction of a mixture of Cp*AlBr2 and AlBr3. The Al(III) atoms of the two crystallographically independent cations each lie on an inversion center, and the [AlBr4](-) anions are on general positions. At 123 K, the structure exhibits disorder in two of the Br atoms of the [AlBr4](-) ion, with a ratio occupancy of 0.733 (6): 0.267 (3). In the crystal, there is possible weak hydrogen bonding between some methyl groups and Br atoms. The interactions link the moieties in a three-dimensional array.
